    tdf#141467 xmloff,sc,sw: ODF export: reorder flys' ZOrder/z-index harder
    
    Also keep the control layer distinct from the foreground, as a follow-up
    to tdf#133487.
    
    Try to improve the detection of already sorted indexes a bit to avoid
    unnecessary sorting.
    
    Hilariously the test docs require adding 3 additional items to the
    extension schema.
